Braille dot delivery system

Abstract

The Braille Dot Delivery System is an enhancement design from the Publication No.: US-2012-0295232-A1, which implements the same concept for delivering Braille Dot characters via electronic pulses; the system comprises of the Low Frequency Pulse Output Device Pad [ 140 ] and the Computer/Signal Transmitter [ 200 ], where the wireless receiving unit receives information from the Computer/Signal Transmitter [ 200 ] generates electrical pulse(s) to replicate a Braille dot-like character. The Low Frequency Pulse Output Device Pad [ 140 ] contain electrodes in a 3×2 matrix cell; each cell consists of a set of electrodes, one for positive signal and another negative signal or ground; completing the circuit is the electrode gel pad, a medium between the electrode cell insert and human skin surface contact, there delivers an electronic pulse at low applied current. The Computer/Signal Transmitter [ 200 ] allows for creating Braille Dot characters by the key buttons and functions as a central processing unit to communicate, transmit, and receives information with other devices like smart phone, tablet, laptop, desktop, World Wide Web, and other communication devices.

The invention claimed is: 
     
       1. A Braille dot delivery system comprising:
 a low frequency output device pad; 
 a frame; 
 frame straps, wherein the low frequency output device pad is configured to attach around a thenar region of a hand with the frame straps; 
 a central processing unit including a transmitter; 
 wherein the low frequency output device pad further comprises a 3×2 electrode cell matrix:
 wherein each cell of the matrix comprises:
 a cell slot with two electrodes separated by an insulator, wherein one electrode is positive (+) and one electrode is negative (−); and 
 a gel pad positioned in the cell slot; 
 
 
 wherein the low frequency pulse output device outputs a low electrical pulse capable of passing an electric current through human skin whereby a human can sense the electrical pulse.
